Class T fuses are recognized for their compact form factor relative to their current rating and their ability to clear high-level fault currents rapidly. This fuse is installed by licensed electricians in panelboards, switchboards, and disconnect enclosures where reliable overcurrent protection is required. Its current-limiting action helps protect downstream equipment from damage during fault conditions.\u003c\/p\u003e\u003cp\u003eThe A3T400 is suited for use in industrial facilities, commercial buildings, and heavy-duty electrical distribution applications where 400-amp overcurrent protection is required. Class T fuses are commonly specified in systems where space constraints make their compact dimensions an advantage over larger fuse classes. Installation is performed by qualified electricians following applicable NEC requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass T fuse construction for high-fault-current interrupting capacity\u003c\/li\u003e\n\u003cli\u003e400-amp current rating for heavy-duty overcurrent protection\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps protect downstream components during fault events\u003c\/li\u003e\n\u003cli\u003eCompact form factor relative to ampere rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fuse for Class T fuseholders rated at 400 amps in commercial and industrial electrical distribution equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit completely before removing or installing any fuse. Verify the fuseholder is rated for Class T fuses and matches the 400-amp rating before installation. Never install a fuse in a holder that does not match its class or ampere rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200189028\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3T400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383902437682,"sku":"A3T400","price":235.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677637.jpg?v=1782611202","url":"https:\/\/voomisupply.com\/products\/merit-brass-a3t400-class-t-fuse-400-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
